HTML Coding Header Help (w screenshots)

I am excited to have an up and running Gallery linked to my wordpress blog. I used the wpg2 plugin which worked perfectly. The only only problem is that there is no link back to my blog page once i am in my gallery. Of course, they can always hit the browser "back" button to get to it, but i was hoping to also put in a link on my page for a cleaner navigation.

Problem is I dont know HTML.
I used Foxbug to assist me in inspecting the header element. The first attached file is what it came up with.

The second attachment shows what I want to do, which is to move the existing image over to the center, and then add a link to my page in the same font that says "Back to Blog"

Can someone assist me in editing the html?

Thanks!
